My vote...

1. Brio AT - same 1.3 engine as the 2nd gen Jazz... (big plus for me)
2. Mirage GLX AT - close second (If I remember correctly, mas mahal ang Brio, if budget will be an issue I will vote for the Mirage over the Brio)

Kung Automatic, I prefer cars with bigger engines with 4 cylinders. Kaya lang, ang daming horror stories ng Chevrolet (parts availability)

Dun naman sa next list mo...

1. Jazz - I love the flexibility of the seats... Plus sa choices mo, AT sya
2. Adventure - tried and tested, magkamali ka lang ng gear iitim na usok ng Diesel...
3. Mobilio - My wife loves this car, kaya lang sya nasa bottom kasi you mentioned MT
